Re: [linux-audio-user] Decent reverb, and DSP in hardware?

by davidrclark＠earthlink.net

Mark C., A couple of days ago, you posted: > tool that it would be better in 90% of usage cases that a > simple set of reliable but convincing presets Past history, current use, and the proliferation of reverb models strongly suggest that users don't agree what the presets should be, and that's the problem. Even so, I did offer a set to those who request. You also suggested that I somehow "condemned" you to "never use" my programs. Linux is user-supported software. Anyone who uses any type of Linux software, whether it be audio or whatever, should be prepared to roll up their sleeves and work on the software as well as "just make music," or whatever they really wanted to do. Those who aren't willing to do this condemn themselves. Now I realize that getting really involved is tough, but anyone who would be critical should understand that I didn't know anything about all this when I started out, either. I especially hate working on GUI's, yet I learned all about Gtk+ and Glade, then created some for potential users --- so I'm "walking the walk." --------------------------------- To a more general audience: I would strongly encourage anyone who wants to "just make music" or "just whatever" to go back to Windows or Mac. Such people who insist on trying to use Linux because they despise Microsoft or Bill Gates or because they want to make some sort of political statement are setting themselves up for repeated disappointment and disillusionment. This message should be communicated more often than it is, especially here in Linux Audio or other multimedia where Linux is far, far behind Windows and Mac for general users. What I see is that most LAUer's who claim that they "just want to make music" also "want to save money," "want to stick it to Microsoft," "want to use only open source software" and so on.... Regards, Dave.

[linux-audio-user] ams PCM input?

by Paul Coccoli

How can I get the line in from my soundcard routed into ams? I tried adding a PCM IN module and a PCM OUT module, then connecting them together. I've connected the ams out to alsa_pcm playpack 1 and 2, and alsa_pcm captures 1 and 2 are connected to the ams ins (I did all that with qjackctl). I know jack and everything else are working because I can load the example_basic.ams patch, plug in my USB contoller, connect them in qjackctl and hear the output. What I want to do now is send the signal from my bass guitar into ams, then back out (i.e. use it as an effect processor). Also, is there a module that will convert an audio signal to CV? I know MCV converts MIDI to CV. Finally, is there another modular synth-type app that makes what I'm trying to do any easier?

Re: [linux-audio-user] midicomp (yet another text 2 midi converter)

I've found more references at linux-sound.org: - Folly: a text-to-MIDI program written in Perl/Tk Dead link, http://homepage.ntlworld.com/serissa/ - Midge: Midi sequencing from the comfort of your text editor http://www.dmriley.demon.co.uk/code/midge/ (This is a Perl based programming tool) - GMC: Guenthers Midi Compiler, a tool to convert text to midi. http://www.geocities.com/SiliconValley/Software/8918/linux/index.html Both Midge and GMC are based on some kind of music description languages. In this area is worth to mention Lilypond because it generates MIDI files and nice scores at the same time, using also an input text describing the music. OTOH, midicomp and midicsv are very similar, based on a text format representation very near to the SMF format. > There is even a pure PHP based implementation of the same old > codebase somewhere on the net... a neat way for a website to > manipulate MIDI files online. I think you mean this one (PHP MIDI Class) http://staff.dasdeck.de/valentin/midi/ Regards, Pedro

[linux-audio-user] ALSA drivers don't stick...

by Erik Thorsson

I have to run 'alsaconf' every time I boot my Debian Sarge 2.6.8-1 box to get sound to work. It detects the 'intel8x0 Silicon Integrated Systems [SiS] Sound Controller (rev a0)'. I say 'OK'. It says... Configuring snd-intel8x0 Do you want to modify /etc/modprobe.d/sound (and /etc/modprobe.conf if present)? I say 'Yes'. (incidentally, /etc/modprobe.conf doesn't exist. /etc/modprobe.d/sound reads... options snd device_mode=0660 alias snd-card-0 snd-intel8x0 alias sound-slot-0 snd-intel8x0 [EOF]) It says... OK, driver snd-intel8x0 is configured. I say 'OK'. Woohoo. Sound works. Until I reboot... I have 'i810_audio' (the OSS driver, right?) blacklisted in /etc/hotplug/blacklist along with these... acquirewdt advantechwdt alim1535_wdt alim7101_wdt cpu5wdt eurotechwdt i810_tco <--- !!! i8xx_tco <--- !!! ib700wdt indydog machzwd mixcomwd pcwd pcwd_pci pcwd_usb sa1100_wdt sbc60xxwdt sc1200wdt sc520_wdt scx200_wdt shwdt softdog w83627hf_wdt w83877f_wdt wafer5823wdt wdt285 wdt977 wdt wdt_pci usb_midi usb_audio i810_audio <--- !!!

[linux-audio-user] Using DAT start ids to record separate wavs

by Wolfgang Woehl

Is there an automated way to create separate wav files from a DAT's SPDIF stream using the start ids, something like DAT -> SPDIF -> hdsp -> 1.wav 2.wav ... ? Wolfgang

[linux-audio-user] Re: [linux-audio-announce] [ANN] MIDI to CSV Utilities 1.0

by Pedro Lopez-Cabanillas

Yes, it can be very useful for debugging purposes, but it is not limited to that. Perhaps it has something to do with the fact that John Walker lives in Switzerland, but his tool is like a Swiss Army Knife. > More information: > http://www.fourmilab.ch/webtools/midicsv/ A little quotation from Fourmilab: MIDI music files are a simple and elegant representation of musical compositions, but are stored in a somewhat arcane binary format which is difficult to process without specialised libraries. MIDICSV includes two utilities, midicsv and csvmidi, which inter-convert MIDI files and Comma-Separated Value (CSV) files preserving all information. CSV representations of MIDI file may be loaded into spreadsheets and database programs, and can be easily processed with text processing languages such as Perl and Python. A variety of examples, written in Perl, illustrate generation and transformation of MIDI music files in CSV format. Complete source code in portable ANSI C and ready-to-run WIN32 executables are available. Regards, Pedro

[linux-audio-user] LAU podcasting

by Mark Constable

Just an idea but if anyone with recording gear (probably most people on this list) then please consider creating some podcasts of how you run your setups with examples of software techniques you use to create your music on linux... especially in ogg :-) There is finally a reasonable channel for publishing 30 to 40 minute lo-fi shows and there is already enough good and bad material abounding but nothing like linux nerds describing and demonstrating their audio wares. For those not aware of podcasting (it's NOT just for Macs), this is arguably the best example of the genre and I am amazed at the quality of this guys 64kbit/22khtz productions from his Mac... can we on linux match this fine level of production ? I'd like to think so, and hear so. http://homepage.mac.com/dailysourcecode/DSC/DSC-2005-01-26.mp3 The presence and seperation of some of the radio-like cuts are excellent considering the bitrate used. --markc

[linux-audio-user] dssi segfault

by Matthew Allen

I have been trying to get dssi up and running on my machine this afternoon and I have run into a snag. It appears to compile correctly (both CVS and tarballs). But whenever I try to do the tests I get a segfault. I know its some user error, but its difficult to track down with only a segfault. Is there a common mistake I am doing? thanks m.

[linux-audio-user] Re: Decent reverb, and DSP in hardware?

by Juhana Sadeharju

I need that reverb impulse response which creates good vocal (say) sound. You may forget all other effects now. Only the pure delay + echo + reverb combination. Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software

[linux-audio-user] Re: Decent reverb, and DSP in hardware?

by Juhana Sadeharju

OK. I will look at the reverb problem. I want to have the impulse responses of known good reverbs for: (1) Vocals. (2) Guitars. (3) Flutes. (4) Drums. Check impulses at "http://www.noisevault.com" or record yourself. Please convert to wav format and upload to ftp://ftp.funet.fi/incoming/audio/ Were (1)-(4) the most wanted reverb settings? What else? How to get most spacious but nearby vocals? Does people use other effects together with reverb for vocals? I can provide examples of good vocals if you want to examine them.
